Thank you very much. I enjoyed the video. I have been testing various ways of dipping powder and tapping. I made test measures at different powder volumes of the same powder. I could tap and come up with a weight that exceeded the volume setting. This is why I was asking so many questions and I hope I did not make anyone mad. I am just trying to learn.
When I ask about the RCBS powder trickler, mine is old. I know it is non magnetic and possibly aluminum. I did not want an accident from sparking. I interested about the Hornady trickler being plastic, if it would create a static charge.
I can see all the points the man in the video made. I am going to use the Law of Diminishing Returns which the man was referring to. I will fire 5 shots using 60, 70, 80, 90, and 100 grV. I have an Oehler 35P chronograph which I will measure the velocity. This will be an interesting test to run at the range to see the various velocities.
